The VersaBoard is pretty amazing. The ability to train your base with resistance is important on both sides of the ball. Basically you can connect it to anything without having to do any alterations to your equipment. I love the idea of attaching it to Tackling sleds as well. Now I don’t have to train the bag holders as much as I train my players. I love the fact you don’t have to watch film on the drill to show the athlete he’s lost his base…if the boards disconnected you lost your base. Just awesome.
